用递归的方法编写函数求Fibonacci级数的源程序

这是通过制作一个简单的程序开始代码视觉的一课。

可编程并行接口８２５５Ａ完成的交通灯实验 　 　　用８２５５Ａ的Ｂ端口和Ｃ端口控制１２个ＬＥＤ的亮和灭（输出为０则亮，输出为１则灭），模拟十字路口的交通灯。 -programmable parallel interface 8255A completed, the traffic lights experimental 8255A port B and C- I control 12 LED bright and methomyl (output of 0-liang, the output of an anti), the simulation of traffic lights at a crossroads.

界面转换，适合初学者学习，学习界面的基础知识简单易懂还有一些控件的最基本的应用可以对照学习添加其他相关程序想学习的请过来下载

交通灯的变换----汇编语言实现-Traffic lights change---- assembly language to achieve

LCD显示,能够滚动显示数字频率,按键的号码

此程序的功能是实现不通过外设而直接发出声音,程序里用到主程序调用辅助的程序实现语言是汇编语言-this procedure is the function peripherals is not passed directly to voice their opinions. Lane procedures used in the main program called auxiliary program language is assembly language

一个的usb源码，提供给大家参考一下，有什么问题请指教-a source of usb, to refer to, what issues please enlighten

     为烫发器程序,热敏电阻做的采样,精确到正负0.5摄氏度,量产程序,大家拿去用吧.

片机电子钟的计时脉冲基准是由外部晶振的频率经过12分频后提供，采用内部的定时/计数器来实现计时功能。所以，外接晶振频率精确度直接影响电子钟计时的准确性。 -Machine electronic time clock pulse baseline is by an external crystal oscillator frequency, after 12 minutes after the frequency, using an internal timer/counter to achieve the timing function. Therefore, the external crystal frequency accuracy of a direct impact on the accuracy of the electronic time clock.
